Ok so that about conferms it. That is the element talking. The things she mentions arnt memories of human hosts. The twin candidates were almos all stillborn or died in infancy if I remember right. So the element had no eyes or ears most of the time. Just waiting on a host but losing it instantly. So the null is much more a threat to her as it will give the host control. It also explains the whole memories thing, they all are the same being, not just inherited.
